NANO: Network Access Neutrality Observatory
نویسندگان
چکیده
We present NANO, a system that establishes whether performance degradations that services or clients experience are caused by an ISP’s discriminatory policies. To distinguish discrimination from other causes of degradation (e.g., overload, misconfiguration, failure), NANO uses a statistical method to estimate causal effect. NANO aggregates passive measurements from end-hosts, stratifies the measurements to account for possible confounding factors, and distinguishes when an ISP is discriminating against a particular service or group of clients. Using simulationwe demonstrate the promise of NANO for both detecting discrimination and absolving an ISP when it is not discriminating.

Broadband Internet: Net Neutrality versus Open Access
“Network neutrality” and “open access” are two policies designed to preserve openness on the Internet. Open access mandates openness of conduits (e.g. television cable and DSL) to intermediaries (e.g. America Online), while network neutrality mandates openness to advanced content (streaming video, interactive e-commerce, etc.). We develop a systems model with free entry and competition in all t...
متن کاملNetwork neutrality on the Internet: A two-sided market analysis
We discuss network neutrality regulation of the Internet in the context of a two-sided market model. Platforms sell broadband Internet access services to residential consumers and may set fees to content and application providers on the Internet. When access is monopolized, cross-group externalities (network effects) can give a rationale for network neutrality regulation (requiring zero fees to...
متن کاملThe economics of network neutrality
Under the current regime for Internet access, “network neutrality,” parties are billed only by the Internet service provider (ISP) through which they connect to the Internet; pricing is not contingent on the content being transmitted. Recently, ISPs have proposed that content and applications providers pay them additional fees for accessing the ISPs’ residential clients, as well as fees to prio...
متن کاملNetwork Neutrality, Broadband Discrimination
Communications regulators over the next decade will spend increasing time on conflicts between the interests of broadband providers and the public’s interest in competitive innovation environment on the internet. As the policy questions this conflict raises are basic to communications policy, they are likely to appear in many different forms. So far, the first major appearance has come in the “...
متن کاملNetwork Neutrality: Regulating with More Questions Than Answers
“Network neutrality,” while subject to varying definitions, can be summed up as the principle that “all like Internet content must be treated alike and move at the same speed over the network. The owners of the Internet’s wires cannot discriminate.” The policy implication is that network operators should not be allowed to “create different tiers of online service” by selling different levels of...
